When I pasted a selection from Preview, the the image is turning black.
The source is a TIFF image (black lines on white background). Using the selection tool to copy a portion of the image, then pasting the selection into a WORD document. The resulting pasted image is entirely black. This also happens when I paste the selection into TextEdit. I use this tool a lot and have not had any problems until I installed OS X El Capitan. I appreciate your help, thanks.
